In this foundational work, Sayyid Qutb meticulously outlines the core characteristics of the Islamic worldview, or 'tasawwur.' He defines its unique principles—such as divine origin, constancy, comprehensiveness, and balance—contrasting them sharply with secular philosophies and man-made ideologies. The book serves as an intellectual cornerstone, explaining how this distinct conception of existence and humanity should govern every aspect of a Muslim's life, from individual belief to societal structure. It is essential reading for understanding the intellectual underpinnings of modern Islamic thought and the all-encompassing nature of the Islamic way of life.
